关于c:C语言实现三子棋

C 语言实现三子棋(通过数组)
须要蕴含的头文件

include <stdio.h>

include <stdlib.h>

include <time.h>

创立一个全局数组
因为如果数组大小变动,游戏规则和实现思路都会有很大的变动,所以不进行宏定义常量来定义数组
char board3;
设计主程序框架
game() 函数为游戏过程框架
int main()
{

do
{
    int i = 0;
    printf("1.Start the game\n");
    printf("2.Quit the game\n");
    printf("Please enter your options->");
    scanf("%d", &i);
    switch (i)
    {
        case 1:
            game();    //game()函数为游戏过程框架
            break;
        case 2:
            return 0;
        default:
            printf("Input error,please enter again!\n");
            break;
    }
} while(1);

}
设计游戏过程框架
void game()
{

initBoard();
srand((unsigned)time(NULL));    // 生成随机种子,前面须要生成随机坐标
char temp = ' ';                // 定义一个字符变量,用于接管前面判断函数返回值,用于决定游戏输赢
do
{printBoard();           // 打印棋盘的函数
    userPlay();             // 玩家下棋的函数
    temp = judge();         // 判断游戏是否分出输赢
    if (temp != ' ')
        break;
    robotPlay();            // 电脑下棋的函数
    temp = judge();} while (temp == ' ');
printBoard();
switch (temp)
{
    case '@':
        printf("User WIN!\n");
        break;
    case '$':
        printf("Bobot WIN!\n");
        break;
    case '*':
        printf("Dogfall !\n");
        break;
    dafault:
        break;
}

}
设计棋盘款式
有趣味的能够搞的更加花里胡哨,这里草草了事,呸,简略设计一下 哈
//##########

//_|_|_

//_|_|_

打印棋盘
重点就在这了,棋盘设计的再牛逼,也得能打印进去才行
这里棋盘设计的比拟繁难,打印起来也比较简单,要害是思路要清晰
void printBoard()
{

printf("##########\n");
int i = 0,j = 0;
for (i = 0; i < 3; i++)
{for (j = 0; j < 3; j++)
    {if (j != 2)
        {printf("%c|",board[i][j]);
        }
        else
            printf("%c\n",board[i][j]);

    }
    if (i != 2)
        printf("_|_|_\n");
}
printf("##########\n");

}
玩家下棋
自己习惯用界面编程的坐标系示意坐标,因而上面赋值时横坐标和纵坐标倒过去了
void userPlay()
{

printf("Please enter coordinates->");
int x = 0,y = 0;
while(1)
{scanf("%d %d", &x, &y);
    if (x > 0 && x < 4 && y > 0 && y < 4)
    {if (board[y - 1][x - 1] == ' ')
        {board[y - 1][x - 1] = '@';
            break;
        }
        else
            printf("There are chess pieces here,please enter again!->");
    }
    else
        printf("Input error,please enter again!->");
}

}

电脑下棋
这里要害是 要生成可行的坐标,以及随机数的生成
void robotPlay()
{

int i = 0, j = 0;
while (1)
{i = rand() % 3;
    j = rand() % 3;
    if (board[i][j] == ' ')
    {board[i][j] = '$';
        break;
    }
}

}
判断游戏输赢
这里就到了最难剖析的一部分了
废话不多说,间接看代码
char judge()
{

int i = 0, j = 0;
    // 判断两条对角线    对 i j 的值不做带动,所以放在后面
if (board[i][j] == board[i + 1][j + 1] && board[i][j] == board[i + 2][j + 2] && board[i][j] != ' ')
    return board[i][j];
if (board[i][j + 2] == board[i + 1][j + 1] && board[i][j + 2] == board[i + 2][j] && board[i][j] != ' ')
    return board[i][j + 2];
    // 顺次判断三行、三列
for (i = 0,j = 0; j < 3; j++)
{if (board[i][j] == board[i + 1][j] && board[i][j] == board[i + 2][j] && board[i][j] != ' ')
        return board[i][j];
}
for (i = 0,j = 0; i < 3; i++)
{if (board[i][j] == board[i][j + 1] && board[i][j] == board[i][j + 2] && board[i][j] != ' ')
        return board[i][j];
}
    // 判断棋盘是否满了(平局)for (i = 0; i < 3; i++)
{for (j = 0;j < 3; j++)
    {if (board[i][j] == ' ')
            return board[i][j];
    }
}
    // 如果没呈现以上状况,轻易返回一个不同符号,使游戏持续进行
return '*';
